Definitions
- the present invention relates to a driving control device for a domestic, electronic sewing machine.
- a needle stop automatic system of the machine is provided by which not only the stop of the needle in predetermined positions is achieved when the current from the regulator is switched off but also the positioning thereof in desired end positions (up or down) by the use of short pulses from the regulator.
- the regulator is actuated by a foot, the operator has both her hands free for handling the work piece.
- the driving motor 11 of the machine is controlled by means of a control circuit comprising a transistor 12 with a base electrode 13 supplied with a control current from the output 14 of the computer.
- An amplifier 15 supplies the motor in dependence of a second control circuit comprising a regulator, e.g. a foot pedal 16 adjusting a potentiometer 17 which changes its resistance in dependence of the position of the pedal.
- a switch 18 in series with the potentiometer is actuated for breaking the circuit
- the control circuit is supplied with a low tension V, which passes via a resistor 19 to a change-over switch 23 and also to the input 20 of a comparator 21 having a second input 22 supplied with another low tension V 2 somewhat lower than the first said.
- the computer makes by controlling the change-over switch a change of the position of this one as shown by continuous lines.
- the tension V constitutes via a voltage divider 26, 27 a control voltage effecting a low, constant r.p.m. of the motor, and the machine runs slowly whereby a sensor 28 at the arm shaft of the machine detects the end positions of the needle.
- a sensor 28 at the arm shaft of the machine detects the end positions of the needle.
- the logical circuits in the computer obtain signals when the needle is "up” or "down".
- the logical circuit for "needle down" is automatically switched in and, provided that the regulator after a moment is inactivated, the machine will run slowly and the needle slowly approach its lower end position. In this position a signal is passed from the sensor 28 on the wire 30 to the corresponding circuit releasing in the computer a break in the control current to the transistor 12.
Abstract
Dispositif de commande d'entrainement, monte sur une machine a coudre electronique possedant un processeur (10) et un systeme automatique d'arret d'aiguille, pourvu de circuits electriques d'entrainement et de commande qui, sous l'effet de courtes impulsions produites par le regulateur du moteur (16), deplacent l'aiguille par intermittence dans les positions elevee et baissee respectivement. Les impulsions pour ce type d'entrainement de la machine peuvent durer au moins la moitie du temps d'un cycle de la machine. Un actionnement plus lent du regulateur produit une marche continue de la machine.Drive control device, mounted on an electronic sewing machine having a processor (10) and an automatic needle stop system, provided with electric drive and control circuits which, under the effect of short pulses produced by the engine regulator (16), intermittently move the needle to the raised and lowered positions respectively. The pulses for this type of machine drive can last at least half the time of a machine cycle. Slower actuation of the regulator produces continuous running of the machine.
